Ocean bottom seismometer survey line OBS2016-2 across the magnetic quiet zone and continent-ocean boundary in the northeastern South China Sea

OBS2016-2 dataset was collect in July, 2016. The ~320 km long NW-SE oriented profile OBS2016-2 is located to the east of the Dongsha Islands, extending from the Chaoshan Depression to the East Subbasin of the South China Sea. Seismic data were collected by R/V Shiyan-2 of South China Sea Institute of Oceanology (SCSIO), Chinese Academy of Science. The seismic sources are composed of four large volume Bolt airguns and the total airgun volume is 6000 in3. The firing interval was 90 s in time and 204 meters in distance, and the sailing speed of R/V Shiyan-2 was about 4.5 knots during the experiment. A total of 1572 shots were fired. Fifteen 4-component broadband OBSs were deployed, and fourteen of them were retrieved successfully with good data records. Data format is SAC.
